The problem with COD/BF/ETC had with imbalancing was that the imbalancing wasn't so called "Realistic" attributes. If they wanted to really be realistic, half of the weapons in FPS will have the same damage, accuracy, and handling, the main difference will be preference, quality of components and caliber. MP40 should not out damage a M1A1 Thompson, but it should have better accuracy and range. M4A1 should have the same damage as a TAR 21, FAMAS, M16, FN SCAR-L, MAGPUL MASADA, and FN F2000. their differences would be in weight, barrel length, accuracy, and fire-rate, but their damage should be the same. M14, M21, FN FAL, and FN SCAR-H will have the same aspects as the last statement.
What people have to realize is that in War Firearms have no balance, you have better weapons and you have crappy weapons. Only the UN will determine what is considered "OP" which is stupid. Since SD is using weapons with influence from real weapons, they can be balanced, COD and others are using real weapons and should be based on the real statistics not on subjective views.

The Hockler will probably have lower damage than the glock, better accuracy by using the VFG, and a bigger clip. It won't change the balance, it will just give a different option.
